Objective

Design the invariants/constraints system that allows customers to express free-form fashion hard lines in natural language. This is a key differentiator — no other service offers this.

The Problem

Existing style quizzes force customers into pre-defined categories. But real fashion constraints are nuanced and personal:

  • "I will never wear anything that requires ironing"
  • "I need at least one pocket in every outfit"
  • "I only wear high-waisted pants"
  • "No synthetic fabrics touching my skin"
  • "I refuse to wear anything with a visible logo"
  • "I need bra-friendly necklines"
  • "I only wear flats, never heels"
  • "Nothing dry clean only — I need machine washable"
  • "Short sleeves only — long sleeves make me overheat"
  • "I can't wear turtlenecks (sensory issue)"
  • "No animal products — vegan only"
  • "I never buy fast fashion"

Design Requirements

Input Method

  • Free-form text field with examples
  • "Tell us in your own words: what are your fashion hard lines?"
  • Suggestions/examples shown below (clickable to add)
  • Can add as many as needed
  • Updated anytime via profile settings

Natural Language Processing

  • Parse free-form text into structured constraints:
    • fabricConstraint: natural only, no synthetics, specific materials
    • careConstraint: machine washable, dry clean OK/NOT OK
    • styleConstraint: no logos, no crop tops, no prints, no specific necklines
    • colorConstraint: never wear yellow, only neutrals
    • `fitConstraint**: high-waisted, oversized only, fitted only
    • practicalConstraint: must have pockets, must be nursing-friendly
    • `ethicalConstraint**: vegan, fair trade, made in USA
    • `sensoryConstraint**: no wool, no tags, no itchy fabrics
    • `occasionConstraint**: office appropriate, date night only, casual only

Enforcement

  • Constraints must be strictly honored (no "we'll try to accommodate")
  • If a constraint would leave zero items in catalog → system flags to human stylist
  • Constraints cascade into curation engine as hard filters (not scoring factors)
  • Exception: "Stretch items" should NOT violate constraints (stretch is about pushing style, not breaking rules)

Language Requirements

  • Must use plain American English throughout
  • No fashion industry jargon
  • No intimidating terminology
  • Examples should feel relatable
  • 80%+ comprehension target (US consumer average reading level)

Deliverable

Constraints system design at product/invariant-constraints.md — NLP parsing schema, constraint categories, enforcement rules, UX copy for the input screen, and examples of effective constraint patterns.

## Objective Design the invariants/constraints system that allows customers to express free-form fashion hard lines in natural language. This is a key differentiator — no other service offers this. ## The Problem Existing style quizzes force customers into pre-defined categories. But real fashion constraints are nuanced and personal: - "I will never wear anything that requires ironing" - "I need at least one pocket in every outfit" - "I only wear high-waisted pants" - "No synthetic fabrics touching my skin" - "I refuse to wear anything with a visible logo" - "I need bra-friendly necklines" - "I only wear flats, never heels" - "Nothing dry clean only — I need machine washable" - "Short sleeves only — long sleeves make me overheat" - "I can't wear turtlenecks (sensory issue)" - "No animal products — vegan only" - "I never buy fast fashion" ## Design Requirements ### Input Method - Free-form text field with examples - "Tell us in your own words: what are your fashion hard lines?" - Suggestions/examples shown below (clickable to add) - Can add as many as needed - Updated anytime via profile settings ### Natural Language Processing - Parse free-form text into structured constraints: - `fabricConstraint`: natural only, no synthetics, specific materials - `careConstraint`: machine washable, dry clean OK/NOT OK - `styleConstraint`: no logos, no crop tops, no prints, no specific necklines - `colorConstraint`: never wear yellow, only neutrals - `fitConstraint**: high-waisted, oversized only, fitted only - `practicalConstraint`: must have pockets, must be nursing-friendly - `ethicalConstraint**: vegan, fair trade, made in USA - `sensoryConstraint**: no wool, no tags, no itchy fabrics - `occasionConstraint**: office appropriate, date night only, casual only ### Enforcement - Constraints must be strictly honored (no "we'll try to accommodate") - If a constraint would leave zero items in catalog → system flags to human stylist - Constraints cascade into curation engine as hard filters (not scoring factors) - Exception: "Stretch items" should NOT violate constraints (stretch is about pushing style, not breaking rules) ### Language Requirements - Must use plain American English throughout - No fashion industry jargon - No intimidating terminology - Examples should feel relatable - 80%+ comprehension target (US consumer average reading level) ## Deliverable Constraints system design at `product/invariant-constraints.md` — NLP parsing schema, constraint categories, enforcement rules, UX copy for the input screen, and examples of effective constraint patterns.

✅ Design/planning ticket with substantial content. Contains complete NLP-driven invariants system with 9 constraint categories (fabric, care, style, color, fit, practical, ethical, sensory, occasion), enforcement rules, and UX copy guidelines. A key differentiator. Keeping open as a feature.

✅ COMPLETED: Invariants & Constraints design document written at product-design/invariants-constraints.md (10KB). Covers: constraint taxonomy (6 types: hard no's, soft preferences, positive invariants, situational, seasonal, budget boundaries), data model, matching algorithm integration (Stage 3), learning loop with auto-suggestion, UX flows for onboarding/editing/feedback, edge case resolutions, integration points.
